The best we've got is a compound called tantalum carbide, which can handle about 4,000 degrees Celsius max.

我们最好的材料是一种叫做碳化钽的化合物，它可以承受最高约 4000 摄氏度的温度。

This is a tantalum capacitor. Or at least we think it's a tantalum capacitor.

这是一个钽电容。者至少我们认为它是一个钽电容器。

Tantalum is an element that's derived from an ore called columbite-tantalite, or coltan.

钽是一种元素，源自一种叫做钶钽钶钽的石。

2 mm in diameter. Tantalum, haven't got a clue what it's used for.

径0.2毫米。钽，完全不知道它有什么用途。

Tantalum is highly sought after because it's got a very high melting point and it resists corrosion.

钽之所以备受追捧，是因为它具有非常高的熔点并且耐腐蚀。

The recovery of tin was recently added, says Mr Bormann, with zinc, gallium and tantalum planned for next year.

博尔曼先生说，最近又增加了锡的回收，并计划明年增加锌、镓和钽的回收。

That is possible because this part of the transistor is made of tantalum pentoxide, a material whose atoms are arranged in a lattice which contains holes large enough for copper atoms to squeeze through.

这是有可能现的，因为这部分晶体管是由五氧化二钽制造的——这种材料可以将它自身的原子排布在晶格中，这些晶格包括一些足够大的孔，可以让铜原子挤过去。

But essentially there are 3 key groups  of materials that are added or deposited onto the wafer: metals such as copper or tantalum,   insulators which are typically called oxides, and crystalline layers of silicon.

但本质上，有三组主要材料被添加沉积在晶圆上：铜钽等金属、通常称为氧化物的绝缘体和硅晶体层。
